A new parameter was introduced in PT8.54 and backported to PT8.52.23 and PT8.53.13 in the Database Options section of the process scheduler configuration file (psprcs.cfg). EnableAEMonitor controls whether Application Engine calls DBMS_APPLICATION_INFO. The default value for this parameter is 0.

The PeopleSoft support document does not reference the database bug report, but it seems reasonable to infer that the new parameter was introduced to work around the database bug.

This new parameter is not described in PeopleBooks until PeopleTools 8.55. It does appear in the delivered configuration files on at least 8.53.13. However, it is not present in the delivered 8.54.05 configuration file (bug 21055140). Therefore, by default, Application Engine will not set the module and Action unless you add it to the configuration file.

My Recommendation

I certainly think that you should add this parameter to all process scheduler configuration files at relevant PeopleTools version. Unless you specifically have the problem described in the support note, I recommend that you also set the parameter to 1 as shown above. I have never seen the problem in affected database versions, and it is fixed in the terminal release of 11g.

Without setting the parameter, you will lose the ability to relate Enterprise Manager and ASH data to specific application engine steps. If you need to make a code change to achieve a performance improvement you will have to go through the manual process of finding the SQL in an application engine trace.
